Check Digit Verification of cas no

The CAS Registry Mumber 528521-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,5,2 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 528521-80:
(8*5)+(7*2)+(6*8)+(5*5)+(4*2)+(3*1)+(2*8)+(1*0)=154
154 % 10 = 4
So 528521-80-4 is a valid CAS Registry Number.

Synthesis of spiro diphosphines and their application in asymmetric hydrogenation of ketones

Xie, Jian-Hua,Wang, Li-Xin,Fu, Yu,Zhu, Shuo-Fei,Fan, Bao-Min,Duan, Hai-Feng,Zhou, Qi-Lin

, p. 4404 - 4405 (2007/10/03)

Synthesis of chiral diphosphine ligands containing a spiro scaffold was described. The ruthenium complexes of these spiro ligands were found to have extremely high activities (S/C up to 100000) and enantioselectivities (ee up to 99.5%) in the asymmetric hydrogenation of aromatic, heteroaromatic, and α,β-unsaturated ketones.
